A2 Coronal split/pincer fracture
Definition
Type A2 is a coronal split or pincer fracture involving both endplates without involvement of the posterior wall of the vertebral body.
A-type injuries are in general a failure of anterior structures under compression with intact tension band.
Caution: If this fracture is seen at the cervicothoracic junction, it is likely that this is part of a type B or type C injury.
X-ray/ CT
CT/radiograph images are examined to determine the fracture type.
This CT show a sagittal reconstruction of an
C3 type A2 fracture.
For a complete classification (AOSpine Cervical classification) of the injury, and for the management decisions, the following aspects must be considered.
- Neurology
- Facet injury
- Clinical modifiers
